Description
703647 CA Patent LIGHTWEIGHT TOOL FOR CRIMPING A FLANGE COVER
Field of the Invention The invention relates to a tool for affixing one element to another. More specifically, the invention relates to a tool for crimping a flange cover over a flange of a motor vehicle.
Background of the Invention In the complex manufacturing of complex assemblies, it is often required to finish one part by covering it by another. With a motor vehicle, an example of an area where a part is formed over another part is in an opening providing access to a passenger compartment. In the construction of the motor vehicle, a flange extends out around the periphery of the access opening. That flange is covered with a flexible material allowing a door to abut up thereagainst and distort the flexible material slightly to create a seal between the door and the access opening. This is one example of many situations where a part is designed to cover another part.
One problem associated with the design of one part covering another part is the proper securing of the covering part over the underlying structure. Often times, the resulting cover part is crimped over the underlying structure. One example of a tool used to crimp a cover over an underlying structure, such as a flange, is disclosed in United States Patent 5,875,670. In this disclosure, a drive means forces one roller into a second roller to crimp a cover over the flange. A biasing means forces the movable roller axially away from the other roller when no pressure from the drive means is being applied against the first roller. The biasing means is a spring which routinely fails over time. This results in a tool that must be consistently serviced. In addition, the spring reduces the effective pressure of the roller because it is always applying a force against the closing pressure. It is a non-removable bias applying constant pressure against the closing pressure.

Detailed Description Of The Preferred Embodiments Referring to Figure 1, a motor vehicle 10 is shown partially cut away. The motor vehicle 10 has a passenger compartment 12, a side door 14 and an access opening, generally shown at 16. The access opening 16 defines a periphery 18 which extends thereabout which is substantially identical to the outer periphery of the side door 14. An underlying structure 20 extends along at least a portion of the periphery 18 of the access opening 16. In the embodiment shown, the underlying structure 20 is a flange extending out from the motor vehicle 10 into the access opening 16 along the periphery thereof. It should be appreciated by those skilled in the art that the underlying structure 20 may be a structure other than a flange in an access opening 16.
A cover part 22 covers the underlying structure 20 along the entire length of the underlying structure 20. The cover part 22 is, in many times, a composite of two materials having varying resiliency. An internal component is typically a metal which, while flexible, is not resilient in that it does not spring back to its original form once it is bent. The cover part 20 typically includes an outer component which is resilient and springs back to its original form after a deforming force is removed therefrom. The resilient material is a rubber-like material that is used to seal the access opening 16 when the side door 14 abuts thereagainst. The metal component of the cover part 22 is molded inside the resilient component such that the cover part 22 appears to be a rubber piece with no metal component visible.
A crimping assembly is generally indicated at 24 in Figure 1. The crimping assembly 24 crimps the cover part 22 over the underlying structure 20 securing the cover part 22 thereto. The cover part 22 has a U-shape and its two longer legs are crimped against the underlying structure on either side thereof. The crimping 703647 CA Patent assembly 24 does this by applying a force inwardly against the cover part 22 on either side thereof after the cover part 22 is positioned over the underlying structure 20. The crimping assembly 24 squeezes the cover part 22. The crimping assembly 24 is a pneumatic tool and receives its power from an air supply through an air line 26. The use of air pressure through the air line 26 will be discussed in greater detail subsequently.
Referring to Figure 2, the crimping assembly 24 is shown, partially cut away.
The crimping assembly 24 includes a base 28. The base 28 is also a housing covering the inner workings of the crimping assembly 24. The base 28 includes a slot 30 that allows first 32 and second 34 rollers to extend out therefrom. The base 28 provides two optional positions for the pneumatic motor 52, i.e., in a horizontal or vertical position to cover the variety of different flange openings (as shown in Figure 5). The pneumatic motor 52 at position 36 can be orientated to any position within 180 degrees of base 28 (Figure 6). The pneumatic motor 52 at position 38, shown in phantom, remains at 90 degrees to the rollers 32, 34 (Figure 7). In every position, the pneumatic motor 52 acts as a handle for the crimping assembly 24.
The first 32 and second 34 rollers have first 40 and second 42 roller axles with first 44 and second 46 roller pads fixedly secured to the roller axles 40, 42 about distal end 48, 50 thereof.
Referring to Figure 3, the crimping assembly 24 is shown in cross section.
The crimping assembly 24 includes a pneumatic motor 52, which is operatively connected to an output gear 53. The pneumatic motor 52 is housed within the handle 38 and in communication with the air line 26. Compressed air from an air source is fed through the air line 26 into the handle 38. The pneumatic motor 52 receives the air and transforms the compressed air into rotation of the output gear 53.
The rotation of the output gear 53 by the pneumatic motor 52 engages a transmission, generally indicated at 54. The transmission 54 includes a shaft which extends along the base 28 perpendicular to the first 40 and second 42 roller axles. The shaft 56 has a cross section in the shape of a polygon (best shown in 703647 CA Patent Figure 4) and will be discussed in greater detail subsequently. The pneumatic motor 52 engages a fixed miter gear 58. The fixed miter gear 58 is referred to as a fixed miter gear 58 because it is fixed in position with respect to the base 28. The fixed miter gear 58 is secured in place using bearings 60. The fixed miter gear 58 engages a first roller miter gear 62. The fixed miter gear 58 rotates the first roller miter gear 62, which is keyed to the first roller access 40 at an end opposite the distal end 48 thereof.
Miter gears are used to allow different orientations between the shaft 56 and the axles 40, 42 without losing the ability to rotate the roller axles 40, 42. As is shown in Figure 6, the miter gears 58, 62 allow the pneumatic drive 52 to be positioned anywhere within 180° of the base 28.
The shaft 56 extends through the fixed miter gear 58. Because the shaft 56 has a polygon cross section, the rotation of the fixed miter gear 58 also rotates the shaft 56. The rotation of the shaft 56 rotates a movable miter gear 64. The movable miter gear 64 rotates a second roller miter gear 66 which is fixedly secured to an end of the second roller axle 42 opposite the distal end thereof. The movable miter gear 64 is movable because it is not fixedly secured with respect to the base 28 and is movable along the shaft 56. Again, because the shaft 56 has a cross-sectional shape of a polygon, the movable miter gear 64 can move axially along the shaft 56 without creating lost motion between the shaft 56 and movable miter gear 64. The first roller 32 and second roller 34 are housed, together with their fixed miter gear 58 and movable miter gear 64, respectively, inside roller housings 68, 70. Each roller housing 68, 70 has a main body 72, 74 and a gear leg 76, 78 extending down therefrom. It is the roller housing 68, 70 that maintains the fixed spatial relationship between the fixed miter gear 58 and the first roller 32 as well as the movable miter gear 64 with respect to the second roller 34. Both the first roller 32 and the second roller 34 include a plurality of bearings 80 which allow the first 32 and second 34 rollers to roll with respect to the roller housing 68, 70.
The crimping assembly 24 also includes a second roller pneumatic chamber 82 which is in fluid communication with the pneumatic motor 52. An air line 84 is in fluid communication with the pneumatic motor 52 and supplies air under pressure to the second roller pneumatic chamber 82. A valve 86 directs the flow of air through 703647 CA Patent the air line 84 into the second roller pneumatic chamber 82. When pressure builds up in the second roller pneumatic chamber 82, a diaphragm 88 is forced in a direction toward the second roller 34. A diaphragm shaft 90 forces the roller housing 70 toward the first roller housing 68. This, in turn, forces the second roller 34 toward the first roller 32 which will crimp the cover part 22 over the underlying structure 20.
A slide 92 extends between the roller housings 68, 70 and acts as a guide for the roller housing to move with respect to the roller housing 68 associated with the first roller 32. In the preferred embodiment, there is a slide 92 on either side of the roller housing 68, 70. Movement of the roller housing 70 forces the movable miter gear 64 to move along the shaft 56. The movable miter gear 64 can move axially along the shaft 56 while still rotating due to rotation of the shaft 56 as it is powered by the pneumatic motor 52.
When the crimping assembly 24 is to be released, the valve 86 is switched such that the air pressure in the second roller pneumatic chamber 82 is relieved by exhausting the air out therefrom. In addition, the valve 86 forces air into chamber 93.
When pressure builds up in the second roller pneumatic chamber 93, the diaphragm 88 is forced in a direction away from the first roller 32. This moves the second roller 34 away from the first roller 32. The air pressure being injected into chamber obviates any need for a spring force to force the two rollers 32, 34 apart.
The invention has been described in an illustrative manner. It is to be understood that the terminology, which has been used, is intended to be in the nature of words of description rather than of limitation. Many modifications and variations of the invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the invention may be practiced other than as specifically described.
Detailed Description Of The Preferred Embodiments Referring to Figure 1, a motor vehicle 10 is shown partially cut away. The motor vehicle 10 has a passenger compartment 12, a side door 14 and an access opening, generally shown at 16. The access opening 16 defines a periphery 18 which extends thereabout which is substantially identical to the outer periphery of the side door 14. An underlying structure 20 extends along at least a portion of the periphery 18 of the access opening 16. In the embodiment shown, the underlying structure 20 is a flange extending out from the motor vehicle 10 into the access opening 16 along the periphery thereof. It should be appreciated by those skilled in the art that the underlying structure 20 may be a structure other than a flange in an access opening 16.
A cover part 22 covers the underlying structure 20 along the entire length of the underlying structure 20. The cover part 22 is, in many times, a composite of two materials having varying resiliency. An internal component is typically a metal which, while flexible, is not resilient in that it does not spring back to its original form once it is bent. The cover part 20 typically includes an outer component which is resilient and springs back to its original form after a deforming force is removed therefrom. The resilient material is a rubber-like material that is used to seal the access opening 16 when the side door 14 abuts thereagainst. The metal component of the cover part 22 is molded inside the resilient component such that the cover part 22 appears to be a rubber piece with no metal component visible.
A crimping assembly is generally indicated at 24 in Figure 1. The crimping assembly 24 crimps the cover part 22 over the underlying structure 20 securing the cover part 22 thereto. The cover part 22 has a U-shape and its two longer legs are crimped against the underlying structure on either side thereof. The crimping 703647 CA Patent assembly 24 does this by applying a force inwardly against the cover part 22 on either side thereof after the cover part 22 is positioned over the underlying structure 20. The crimping assembly 24 squeezes the cover part 22. The crimping assembly 24 is a pneumatic tool and receives its power from an air supply through an air line 26. The use of air pressure through the air line 26 will be discussed in greater detail subsequently.
Referring to Figure 2, the crimping assembly 24 is shown, partially cut away.
The crimping assembly 24 includes a base 28. The base 28 is also a housing covering the inner workings of the crimping assembly 24. The base 28 includes a slot 30 that allows first 32 and second 34 rollers to extend out therefrom. The base 28 provides two optional positions for the pneumatic motor 52, i.e., in a horizontal or vertical position to cover the variety of different flange openings (as shown in Figure 5). The pneumatic motor 52 at position 36 can be orientated to any position within 180 degrees of base 28 (Figure 6). The pneumatic motor 52 at position 38, shown in phantom, remains at 90 degrees to the rollers 32, 34 (Figure 7). In every position, the pneumatic motor 52 acts as a handle for the crimping assembly 24.
The first 32 and second 34 rollers have first 40 and second 42 roller axles with first 44 and second 46 roller pads fixedly secured to the roller axles 40, 42 about distal end 48, 50 thereof.
Referring to Figure 3, the crimping assembly 24 is shown in cross section.
The crimping assembly 24 includes a pneumatic motor 52, which is operatively connected to an output gear 53. The pneumatic motor 52 is housed within the handle 38 and in communication with the air line 26. Compressed air from an air source is fed through the air line 26 into the handle 38. The pneumatic motor 52 receives the air and transforms the compressed air into rotation of the output gear 53.
The rotation of the output gear 53 by the pneumatic motor 52 engages a transmission, generally indicated at 54. The transmission 54 includes a shaft which extends along the base 28 perpendicular to the first 40 and second 42 roller axles. The shaft 56 has a cross section in the shape of a polygon (best shown in 703647 CA Patent Figure 4) and will be discussed in greater detail subsequently. The pneumatic motor 52 engages a fixed miter gear 58. The fixed miter gear 58 is referred to as a fixed miter gear 58 because it is fixed in position with respect to the base 28. The fixed miter gear 58 is secured in place using bearings 60. The fixed miter gear 58 engages a first roller miter gear 62. The fixed miter gear 58 rotates the first roller miter gear 62, which is keyed to the first roller access 40 at an end opposite the distal end 48 thereof.
Miter gears are used to allow different orientations between the shaft 56 and the axles 40, 42 without losing the ability to rotate the roller axles 40, 42. As is shown in Figure 6, the miter gears 58, 62 allow the pneumatic drive 52 to be positioned anywhere within 180° of the base 28.
The shaft 56 extends through the fixed miter gear 58. Because the shaft 56 has a polygon cross section, the rotation of the fixed miter gear 58 also rotates the shaft 56. The rotation of the shaft 56 rotates a movable miter gear 64. The movable miter gear 64 rotates a second roller miter gear 66 which is fixedly secured to an end of the second roller axle 42 opposite the distal end thereof. The movable miter gear 64 is movable because it is not fixedly secured with respect to the base 28 and is movable along the shaft 56. Again, because the shaft 56 has a cross-sectional shape of a polygon, the movable miter gear 64 can move axially along the shaft 56 without creating lost motion between the shaft 56 and movable miter gear 64. The first roller 32 and second roller 34 are housed, together with their fixed miter gear 58 and movable miter gear 64, respectively, inside roller housings 68, 70. Each roller housing 68, 70 has a main body 72, 74 and a gear leg 76, 78 extending down therefrom. It is the roller housing 68, 70 that maintains the fixed spatial relationship between the fixed miter gear 58 and the first roller 32 as well as the movable miter gear 64 with respect to the second roller 34. Both the first roller 32 and the second roller 34 include a plurality of bearings 80 which allow the first 32 and second 34 rollers to roll with respect to the roller housing 68, 70.
The crimping assembly 24 also includes a second roller pneumatic chamber 82 which is in fluid communication with the pneumatic motor 52. An air line 84 is in fluid communication with the pneumatic motor 52 and supplies air under pressure to the second roller pneumatic chamber 82. A valve 86 directs the flow of air through 703647 CA Patent the air line 84 into the second roller pneumatic chamber 82. When pressure builds up in the second roller pneumatic chamber 82, a diaphragm 88 is forced in a direction toward the second roller 34. A diaphragm shaft 90 forces the roller housing 70 toward the first roller housing 68. This, in turn, forces the second roller 34 toward the first roller 32 which will crimp the cover part 22 over the underlying structure 20.
A slide 92 extends between the roller housings 68, 70 and acts as a guide for the roller housing to move with respect to the roller housing 68 associated with the first roller 32. In the preferred embodiment, there is a slide 92 on either side of the roller housing 68, 70. Movement of the roller housing 70 forces the movable miter gear 64 to move along the shaft 56. The movable miter gear 64 can move axially along the shaft 56 while still rotating due to rotation of the shaft 56 as it is powered by the pneumatic motor 52.
When the crimping assembly 24 is to be released, the valve 86 is switched such that the air pressure in the second roller pneumatic chamber 82 is relieved by exhausting the air out therefrom. In addition, the valve 86 forces air into chamber 93.
When pressure builds up in the second roller pneumatic chamber 93, the diaphragm 88 is forced in a direction away from the first roller 32. This moves the second roller 34 away from the first roller 32. The air pressure being injected into chamber obviates any need for a spring force to force the two rollers 32, 34 apart.
The invention has been described in an illustrative manner. It is to be understood that the terminology, which has been used, is intended to be in the nature of words of description rather than of limitation. Many modifications and variations of the invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the invention may be practiced other than as specifically described.
